OTT "the plugin is disabled because of an error during processing."

I've installed OTT twice, tried different folders but I can never get the right one, or at least it does not work.
I believe it's on the installation, can you tell me where I install it?

FL Studio 12, windows 7, 64 bit.

Try right-click run as administrator and use the FL64 and OTT_x64.dll
if it doesn't work I'm afraid I can't assist further as the freeware comes with no warranty / promise of functionality.

without problems, you can not specify me the directory from where I should install?
Example: C:\Program Files (x86)\Image-Line\FL Studio 12\Plugins\ VST

Directory should not matter, you can select desktop and move the DLL wherever you want, or extract the DLL from the installer exe using 7-zip (freeware)

I have the same issue here. I only run FL & OTT as 64 bit.
When i open FL as Administrator it works and the OTT is "native". When opening it normally in new or old projects it is "bridged" and disabled because of the error.

When I rescan my plugins it also works only the first time (not as administrator) -> also native

I fear that the problem is OTT being bridged somehow. But i don't know how to fix this.
Thanks in advance!

I found the issues. I was unknowingly using the 32 bit version of FL. Now it works perfectly fine!!
